Answer
$9.7$
Work Step by Step
We start with the given expression: $0.1+3.7+5.9$
The commutative property of addition states that changing the order of the addends does not affect the sum.
We use this property to rearrange the addends: $0.1+5.9+3.7$
The associative property of addition states that changing the grouping of the addends does not affect the sum.
We use this property to group two of the addends: $(0.1+5.9)+3.7$
We now simplify using the order of operations:
We first simplify inside the parentheses: $6+3.7$
Then, we add: $9.7$
